Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): ORE ON CONTACT FAULT IS LOW GRADE, FE-STAINED AND CONTAINS LARGE DISADVANTAGEOUS AMOUNT OF BARITE. RICHER ORE WITH LESS BARITE OCCURS IN DOLOMIZED LIMESTONE IN STEEPLY DIPPING FRACTURED ZONES CUTTING THE CONTACT FAULT. IN OK MINE, MINERALIZED ZONE WAS FOLLOWED UP THRU CASTLE BUTTE LIMESTONE TO BELDEN SHALE.

Comment (Location): IN UPPER ASPEN MTN AREA AT TOURTELLOTTE PARK, NEAR HEAD OF SPAR GULCH NE OF JUSTICE MINE AND 700 FT WEST OF SILVER BELL SHAFT. ELEV FROM SPURR (1898). LAT-LONG APPROXIMATED FROM BRYANT (1972) ; INFO FROM LAND.ST :(1980)

Comment (Workings): LAST DOLLAR SHAFT (465 FT DEEP) AND SEVERAL DRIFTS INTERCONNECT WITH JUSTICE, MINNIE MOORE, OK, AND SILVER BELL MINES. THE LATTER VIA APPROX 30-DEG NW-BEARING INCLINES ON CONTACT FAULT. TOTAL LENGTH IS FOR ALL WORKINGS EXCEPT JUSTICE MINE AND OTHER SHAFTS.
